Objective To research the clinical effect of treating sagittal fracture of the mandibular condyle (SMFC). Methods 20 cases of SMFC patients were treated by removing the severe allotopic broken bone block of SMFC and adopting conservative intermaxillary traction. Results All these patients had no adverse side effects such as secondary infection,limitation of mouth opening, arthrocleisis, occlusion disorder and facial deformity. Following-up from the 8th month to the 4th year indicated that their occluding relation and opening movement recovered well. The CT graphs and panoramic radiographs of operated patients discovered that the injured condylar processes had become roughly proper or a little less proper. Conclusion Reasonably removing the severe allotopic broken bone block of SMFC and adopting conservative intermaxillary traction are the more effective methods to cure SMFC ,which is easy to be grasped and popularized.

Asthenospermia accounts for about 30% of the causes of male infertility. Currently, most drugs for asthenospermia lack specificity and desirable therapeutic efficiency. An insight into the pathogenesis of asthenospermia is important for the development of specific therapies for this disease. The protein Na+/K(+)- ATPase α4 isoform (NKA4) presents in both mature testis tissue and the sperm tail, the absence or reduced activity of which may significantly decrease sperm motility. Ouabain is a natural inhibitor of NKA4, suppressing its activity by specifically binding the ouabain site in it. The hypothalamus and adrenal cortex excrete an ouabain-like steroid hormone called endogenous ouabain (EO), which may be associated with the pathogenesis of asthenospermia by inhibiting the activity of NKA4, affecting Na+/H+ exchange, Na+/Ca2+ exchange and sperm cell membrane potential, and eventually reducing sperm motility.

Objective To compare the safety,effectiveness and predictability of laser in situ keratomileusis (LASIK) with fem- tosecond laser (IntraLase) and mechanical microkeratome (Moria M2,head 90?m).Design Prospective clinical study.Participant 148 patients (274 eyes) with high myopia received operation of LASIK.Method The patients were assigned to receiving LASIK with corneal flap creation by Intralase femtosecond laser (134 eyes of 76 patients) or Moria 90 keratome (140 eyes of 72 patients),both groups receiving eximer laser ablation with VISX Star S4.Followed-up examinations such as visual acuity,refraction,wavefront aberra- tion,etc.were scheduled for 1 day,1 week,1 month and 3 months postoperatively.Main Outcome Measures Visual acuity,refrac- tion,wavefront aberration,Schirmer test and tear film breakup time(BUT).Results At 3 months after operation,108 eyes (80.6%) of IntraLase group had UCVA better than or equal to BSCVA preoperatively,showing no statistically significant difference to microker- atome group (116 eyes,82.9%,P=0.642).The mean residual spheroequivalent of refraction of IntraLase group was -0.49?0.70D,show- ing no statistically significant difference to microkeratome group (-0.56?0.83D,P=0.448).The mean Schirmer test of Intralase group was 9.5?4.0mm,showing no statistically significant difference to microkeratome group (9.5?7.2mm,P=0.950).The mean BUT of IntraLase group was 7.9?4.3s,showing no statistically significant difference to microkeratome group (8.08?5.48s,P=0.869).The postoperative higher-order aberrations of the IntraLase group was 0.480?0.133?m,lower than that of microkeratome group (0.578?0.169?m,P=0.034). Conclusions Thin-flap LASIK with femtosecond laser and mechanical keratome flap creation are both safe,effective for the correction of high myopia,showing good predictability and stability.Femtosecond laser has slightly better clinical outcomes than microkeratome.

Objective To investigate the influencing factors for eye cyclotorsion and pupil centroid shift during LASIK.Design Non-controlled retrospective case series.Participant 131 patients (262 eyes) with myopia received bilateral LASIK.Methods Eye cy- clotorsion and pupil centroid shift were measured with Custom Vue~(TM) software during operation and compared with age,gender,right or left eye,flap-making method,spherical equivalent (SE),pupil diameter before and during operation.Main Outcome Measures The de- gree of eye cyclotorsion and distance of pupil centroid shift during LASIK.Results The mean eye cyclotorsion during LASIK was 3.07??2.07?(0?-8.6?).The mean pupil centroid shift was 0.33?0.14 mm (0.04-0.51 mm).The eye cyclotorsion was relevant to preoperative pupil size,difference of pupil size before and during operation,and preoperative SE (r=0.188,0.156,0.130,all P7.0 mm was higher than that of with pupil diameter≤7.0mm (3.35??2.17?,2.71??1.89?,P=-0.014).Pupil centroid shift was higher in fight eyes than that in left eyes (0.39?0.12 mm,0.28?0.13 mm,P=0.000).Conclu- sion Eye cyclotorsion and pupil centroid shift during LASIK can be measured with Custom Vue~(TM) system.The eye cyclotorsion may be influenced by the preoperative pupil size.The pupil centroid during LASIK was more significant in the right eyes than in the left eyes.

We report a case of occult primary spontaneous pneumothorax in a 30 years-old woman. She developed symptoms and signs that were suggestive of pneumothorax. However, chest radiograph failed to reveal pneumothorax. Therefore, we proceeded with computed tomography (CT) thorax which revealed significantly moderate right pneumothorax. The diagnostic approach and the management of this case are discussed.

Objective To explore the feasibility of laparoscopic-assisted partial and subtotal colectomy and per anum intrarectal pull-through procedures for Hirschsprung's disease-allied disorder(HAD).Methods From October 1999 to May 2006,38 infants and children with HAD or Hirschsprung's disease(HD) associated with HAD,to whom conservative treatments proved ineffective or relapse occurred,were treated by laparoscopic-assisted partial or subtotal colectomy and per anum intrarectal pull-through procedures.Four 5 mm trocars were inserted at the edge of umbilicus,right upper,right lower and left center quadarant of abdomen when subtotal colectomy was carried out.Two trocars were placed in the left side,lied in left upper and mid lower quadarant of abdomen respectively.Colon descendens,colon transversum,colon ascendens and ileocecal junction lateral peritoneum were mobilized under laparoscope.The operation on anus was referred to modified Soave procedures.Results 38 patients underwent the operations successfully.Left hemicolon resection were performed in 9 cases,with operation time being 110-180 min(mean,135 min).Subtotal colectomy were performed in 29 cases and colon ascendens were rotated reversal clockwise 270? and pulled down using Deloyers procedures,lengths of remaining colon ascendens being 7-13 cm(mean,11.5 cm),operation time being 140-220 min(mean,175 min),intraoperative blood loss being 15-70 ml(mean,35 ml).Postoperative pathological diagnosis showed 10 cases of intestine neuron developmental anormaly(IND),3 cases of hypoganglionosis(HG),4 cases of immature gangliocyte(IGC),9 cases were not classified,6 cases of HD complicated with IND,2 cases of HD complicated with HG,4 cases of HD complicated with ICG.38 cases were followed up for a mean of 3 years and 5 months(range,6 months to 7 years).9 cases of left hemicolon resection had 1-2 stools per day at 6 months postoperatively without stoma stenosis and constipation recurrence.Conclusions Laparoscopic-assisted partial or subtotal colectomy and radical per anum pull-through procedures for HAD are safe,effect,feasible,with minimal invasion,but some laparoscopic procedure experiences are required.

Objective To study multi-slice spiral CT(MSCT) features of cardiogenic hepatohemia.Methods MSCT features of cardiogenic hepatohemia were retrospectively analysed.Results All cases were showed having reflux of contrast into the inferior vena cava(IVC)during arterial phase,of them,10 cases were accompanied with abnormal hepatic perfusion and 7 cases with intrahepatic lymphostasis sign.Conclusion The features including the reflux of IVC and abnormal hepatic perfusion during arterial phase in contrast-enhanced CT scan may suggest hepatohemia caused by higher pressure level of right heart from the cardiovascular diseases.
